PROBLEM TO BE SOLVED: To properly manage a squeegee by providing the squeegee which can stably hold identification information for management.SOLUTION: A squeegee 52 is provided with four two-dimensional codes 80A to 80D at central parts of two principal surfaces 71, 72 each of which has a rectangular plate-like shape. The two-dimensional codes 80A to 80D respectively correspond to four corner parts along a long side of the squeegee 52, and these corner parts are slid onto a mask thereby scraping solder. Further, with respect to patterns of the two-dimensional codes 80A to 80D, predetermined patterns are formed by parts covered with a carbon-based hard coating 91 and a non-coated part 92 not coated with the coating 91 where surfaces of faces 71, 72 are exposed. |
